AUTOMOBILE v ACK To all whom it may concern:

Be it known that FRANK WALLACE, a citizen of the United States of America, residingat 20 -W. Front St, Youngstowmin the county of Mahoning and State of Ohio, has invented certain new and useful Improvements in Automobile Jacks, of which the following is a specification.

This invention relates to improvements in automobile jacks and has for its principal object to providea simply constructed device having a pivotally mounted bearing block upon which an axle or other suitable part of machine rests when the device is in operation. A further object of the inven tion is to provide an inverted U-shaped member carrying the above mentioned pivotally mounted block, said U-shaped member pivotally secured between the upper ends of'a bifurcated lever.

A still further object of the invention is to provide a device which can be very inexpensively manufactured, of very few parts, and yet be very strong and eflicient.

With the above and many other objects in view, the invention resides in the novel features of construction, and the combined arrangement of parts which will hereinafter bemore particularly described and claimed and shown in the drawings herein:

Figure 1 represents a front elevation of the device.

Figure 2 represents a vertical edge view of the device.

Figure 3 represents a vertical edge view of the device in a position for lifting.

Figure l is a detailed View showing a collapsible handle or lever extension. I

In its preferred embodiment, my invention comprises a support 1 carrying 2 parallel supporting standards 2, to which there is secured a lever 3 fulcrumed at pgints 4 by meansof a fulcrum bolt 5. It will be seen that this lever 3 is bifurcated at its upper end and carries an inverted U-shaped member 6 between the ends 7 of the lever 3. This inverted U-shaped member is pivotally secured to said ends 7 by means of a bolt 8. Centrally located upon the upper surface 9 of the inverted U-shaped' member 6 there is provided a pivotally mounted bearingblock 10. The lower end 11 of the lever 3 is collapsible and folds up by means of a hinge 12. It will not be found necessary to use this lower end 11 except when an extremely heavyweight is to be lifted then in order to start the load upwardly this lower endll may be turned outwardly upon the hinge 12 thereby increasing the leverage. Another function of the'lower end '11 is to act as a stop before the lever 3 reaches an upright position. It will be noticed that I have a sharp lug 13. positioned at the extreme end lt of the lower end 11 of the lever 3. When it is decided to lift'the weight slightly this sharp lug 13 may be used to come in contact with a floor or ground thereby holding the weight suspended upon the pivotally mounted bearing block 10 without giving a full up- .Ward lift by bringing the lever 3 past a dead center when the same comes in contact with a stop 15 and the inverted U-shaped member is brought up against a stop 16. It is, of course, obvious that usually the operator will push the lever 3 down until the dead center is past and comes to rest against the stops l5 and16 as shown in Figures 1 and 2.

From the foregoing description it will-be v I seen that I have invented an extremely simple device by which the whee'lof the automobile or other object, may be readily lifted. It is obvious that this simply construct-- ed jack can be very readily operated merely by one down stroke of the lever 3, and that the device may be positioned underneath the weight to be lifted so that the levermay take varyingfpositio-ns due to the pivotally mounted bearing block 10. Many machines have a brace rod underneath the axle, and

in order to provideia bearing block that will be suitable to different types of machines 1 have therefore provided a recess 17 centrally located upon the top of the pivotally mounted bearing block 10.

hat I claim is;

In a device of the class described a sup-- port member, two parallel support standards, bifurcated lever fulcrumed at the upper ends of said parallel supporting standards, an inverted U-shaped member pivotally secured to the upper end of said-bifurcated lever, a bearing block pivotally setioned within said parallel supporting memposition when the Weight has been elevated 10 bars, an inverted U-shaped member pivotally to its highest point, substantially was desecured within the upper ends of said lever, scribed for the purpose set forth.
